294.31 Tue Jun 3 03:29:27 CEST 2014
30 - work around more 5.20 bugs. backwards compatibility my ass.
31
324.3 Fri Apr 11 06:22:38 CEST 2014
33 - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
34 without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
35 in 5.18. What's so attractive about giving a shit about backwards
36 compatibility - I will never understand.
37
384.2 Sat Jan 25 01:13:14 CET 2014
39 - aio_group could corrupt memory because it didn't restore
40 the stack after req_submit.
41 - be more careful on (e.g. permission) errors in bin/treescan.
42 - work around changes in ExtUtils::MakeMaker.
43 - (libeio) implement aio_realpath for win32.
44 - (xthread) work around compile time bugs in ptw32.
45 - added IO::AIO::pipesize.
46 - (libecb) insignificant update.
47
484.19 Sun Jan 6 12:47:26 CET 2013
49 - avoid endless loop in fiemap with some XFS files.
50 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
51 and call rename/rmdir instead of renameat/unlinkat.
52
534.18 Thu Oct 11 07:01:26 CEST 2012
54 - fix unintended xthread_create by intentionalising it :)
55
564.17 Thu Oct 11 05:19:47 CEST 2012
57 - rename aio_fallocate to aio_allocate, to match documentation.
58 - add list of linux fsid values to aio_statvfs docs.
59 - work around a bug in btrfs' FIEMAP ioctl implementation.
60 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
61 as per unix spec.
62
634.16 Tue Aug 14 05:39:03 CEST 2012
64 - aio_statvfs was wromgly marked for wd emulation, causing
65 it to malfunction for paths.
66 - fix a crash in aio_fiemap, when used on ranges without any
67 extents.
68 - work around linux kernel bug (at least in 3.2): kernel might
69 trash fiemap input arguments.
70 - work around linux kernel bug (at least in 3.2): kernel does not
71 set FIEMAP_EXTENT_LAST on last segment.
72 - work around linux kernel bug (at least in 3.2): kernel silently
73 truncates segment count if a file.
74 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
75 to quick overview.
76 - splice can corrupt data.
77 - (libeio) remove pread/pwrite emulation.
78 - do not grow mmaped scalars in aio_read.
79 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
80 - provide pread/pwrite for win32, making it link again on native win32.
81
824.15 Tue Apr 10 06:59:00 CEST 2012
83 - always include linux/types.h for fiemap, for compatibility to
84 ancient systems (Paul Howarth).
85 - experimental support for IO::AIO::splice and ::tee (no aio_...).
86 - provide SEEK_HOLE and SEEK_DATA, if available.
87 - work around (again!) an immensely stupid bug in RHEL, defining
88 autoconf macros in linux system headers (analysed by Paul Howarth).
89
904.14 Sat Apr 7 02:45:18 CEST 2012
91 - fix stat structure usage on windows, which caused bogus stat results.
92 - (libeio) make readahead emulation behave more like actual readahead by never failing.
93 - new request aio_seek.
94 - new request aio_fiemap.
95 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
96
974.12 Fri Dec 30 08:51:25 CET 2011
98 - realpath would return a random value if the name was too long,
99 instead of -1.
100 - port to c89.
101
1024.11 Mon Oct 10 00:24:11 CEST 2011
103 - libeio didn't compile on !linux (Paul Howarth).
104
1054.1 Sun Oct 9 10:24:11 CEST 2011
106 - IO::AIO did access uninitialised memory on unsuccessful stats.
107 - (libeio) added syncfs syscall wrapper.
108 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
109 - (libeio) support multiple indepenent working directories.
110 - applied speling corrections by Nicholas Bamber.
111 - tune treescan #threads and #outstanding requests a bit.
112 - reduce the number of file descriptors in use at any one time
113 in treescan, to avoid running out of them (and using too much ram).
114 - take advantage of working directoriy abstractions
115 in aio_scandir and treescan.
116 - reduce compiled size by ~10% by not inlining some key functionality.
117 - added --progress switch to treescan.
118
1194.0 Mon Jul 18 05:01:10 CEST 2011
120 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
121 see FORK BEHAVIOUR in manpage for details.
122 - passes testsuite on win32 now and may actually work
123 (activestate 5.10.1 / MSVC6, YMMV).
124 - (libeio) fix a deadlock where a wakeup signal could be missed when
125 a timeout occured at the same time.
126 - (libeio) added realpath.
127 - (libeio) added fallocate.
128 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
129 - (libeio) do not acquire any locks when forking.
130 - (libeio) use fewer time() syscalls when waiting for new requests.
131
1323.93 Wed Jun 29 23:44:18 CEST 2011
133 - ECB.H WAS MISSING.
134
1353.92 Wed Jun 29 14:45:41 CEST 2011
136 - ecb.h was missing.
137
1383.91 Wed Jun 29 13:24:42 CEST 2011
139 - (libeio) work around a Linux (and likely FreeBSD and other
140 kernels) bug where sendfile would not transfer all the requested
141 bytes on large transfers, using a heuristic.
142 - buggy sendfile caused aio_move/copy to sometimes fail for big
143 files (fortunately it checks that the whole file has been
144 transferred...)
145 - use libecb for higher performance and higher portability.
146 - (libeio) disable sendfile on darwin, it's too broken.
147 - disable fork tests on !linux, as only linux supports mixing
148 pthread and fork in perl.
149 - document the fact that fork doesn't work anymore when using
150 this module, on anything !GNU/Linux.
151 - increase timeout in t/04_fork.t, as too many CPAN-tester setups
152 run on a 0.1MHz cpu. Or so.
153
1543.9 Fri May 27 02:43:47 CEST 2011
155 - (libeio) fix memory corruption in aio_readdirx for the flags
156 combination READDIR_STAT_ORDER | READDIR_DIRS_FIRST.
157 - add lots of newer POSIX and GNU/Linux-specific open
158 flags.
159
1603.8 Sun Mar 27 12:25:33 CEST 2011
161 - use nonstandard but maybe-working-on-bsd fork technique.
162 - support a max_idle value of 0.
163 - support setting of idle timeout value (IO::AIO::idle_timeout).
164
1653.72 Fri Feb 11 04:25:38 CET 2011
166 - use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
167 - aio_mknod always used a dev_t value of 0.
168 - new treescan option: --grep.
169 - add more S_IF macros, and major/minor/makedev "macros".
170
1713.71 Thu Dec 30 08:18:46 CET 2010
172 - the numerical result value passed to callbacks did not stringify
173 correctly, due to internal reuse and failure to reset the sv flags.
174 - actually test for posix_[mf]advise, as at least uClibc defines
175 _POSIX_ADVISORY_INFO without actually having any of the required
176 funcitonality. ugh.
177
1783.7 Mon Nov 1 23:00:34 CET 2010
179 - implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
180 aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
181 - document the sad state of affairs w.r.t. pthread on many bsds.
182 - do not enable mmap on systems without _POSIX_MAPPED_FILES
183 (openbsd 4.8).
184 - do not leak memory in IO::AIO::mmap when the scalar already
185 had string-data.
186 - add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
187 them.
188 - cache the result IV, for a minor speedup in the common case.
189 - croak when an mmapped-scalar changes location, to detect
190 user-errors better.
191 - fix aio_readlink prototype.
192
1933.65 Wed Mar 31 02:45:05 CEST 2010
194 - actually use PATH_MAX instead of NAME_MAX for readlink, as to not
195 cut off long pathnames in aio_readlink (based on patch by
196 Rasmus Andersson).
197 - a double fork partially killed the event pipe (great testcase
198 by dormando). affects IO::AIO, BDB and Async::Interrupt.
199 - suck steve's dick and rename our symbols to avoid colliding
200 with nonstandard identifier spam on the broken os x pseudo-os.
201 affects IO::AIO and BDB.
202
2033.6 Mon Jan 11 00:43:39 CET 2010
204 - (libeio) more fixes for the freebsd/apple sendfile - broken by
205 manpage standards, but apparently correct accoridng to actual
206 kernel sources.
207 - add IO::AIO::mmap/munmap support.
208 - add IO::AIO::m(un)lockall support.
209 - clean up manpage.
210
2113.5 Thu Jan 7 21:25:04 CET 2010
212 - (liebio) fix freebsd sendfile (Vanilla Hsu).
213 - (libeio) also fix darwin sendfile that suffered from a similar bug.
214 - add aio_statvfs as interface to statvfs/fstatvfs.
215 - work around buggy symlink() on cygwin in the testsuite.
216 - wtf. freebsd-8.0 actually passes the testsuite! I knew
217 they could implement fork and semaphores one day! cheers!
218
2193.4 Sat Jan 2 15:13:04 CET 2010
220 - (libeio) max_poll_time was not properly converted to ticks.
221 - clarify cancel_subs description.
222 - IO::AIO::sendfile did not actually return the return value
223 from the sendfile call.
224 - implement aio_msync, aio_mtouch.
225 - (libeio) tentatively support darwin in sendfile.
226
2273.31 Thu Nov 12 02:14:29 CET 2009
228 - fix result status documentation of aio_copy, aio_move.
229 - speed up object creation considerably by avoiding
230 hash lookups.
231
2323.3 Wed Aug 5 13:52:58 CEST 2009
233 - use common::sense.
234 - use common schmorp.h header.
235 - allow integers (file descriptors) in addition to file handles.
236 - take advantage of linux' eventfd (but it seems slower on smp?).
237 - use poll not select on posix platforms.
238
2393.261 Wed Jul 1 10:11:51 CEST 2009
240 - more 0S X workarounds (patch by Tokuhiro Matsuno).
241
2423.26 Tue Jun 30 09:33:26 CEST 2009
243 - 0S X of course claims to be posix 2008 but lacks posix_fadvise.
244 try to work around this horribly broken OS in a somewhat hackish
245 way. might help other os's too.
246
2473.25 Sat Jun 27 05:18:26 CEST 2009
248 - added IO::AIO::fadvise and IO::AIO::sendfile.
249 - (libeio) replaced quicksort+insertion sort by a tuned radix
250 sort + insertion sort, resulting in comparable runtime (usually
251 faster) to the old version, but without any ill side effects on
252 degenerated (for quicksort) data.
253 - (libeio) correctly sort dirs by inodes if we have perfect type
254 knowledge and DIRS_FIRST is used.
255 - (libeio) internally the wrong DT_* constants were used, but no
256 known system has differing EIO_DT_*/DT_* values, so not an issue.
257 - removed a (harmless) assert that was left over on the code
258 but should not have been.
259 - use more correct types (change IO length from IV to VAL64,
260 which makes a difference on systems without 64 bit perls).
261
2623.23 Sat Jun 13 16:57:58 CEST 2009
263 - fix off-by-one bug in aio_readdir that was introduced in the
264 rushed 3.22 release.
265
2663.22 Sat Jun 13 15:32:40 CEST 2009
267 - speed up readdirx sort algorithm slightly.
268 - bin/treescan was missing from distro tarball.
269
2703.21 Fri Jun 12 18:45:53 CEST 2009
271 - new options --dirs and --files for treescan.
272 - install bin/treescan by default.
273 - (libeio) aio_readdir can now be cancelled while executing.
274 - fix a printf format string for 64 bit systems (could lead
275 to problems on big endian 64 bit systems).
276 - do not use qsort() but our own algorithm: glibc initialises
277 the whole locale and I/O subsystem inside qsort, causing
278 a stack overflow on 32 bit machines. The new sort uses much less
279 stack and is more than twice as fast in typical situations.
280
2813.2 Sun Jun 7 20:30:05 CEST 2009
282 - (libeio) pwrite emulation was even more flawed than intended and did
283 not restore the file offset.
284 - add aio_readdirx, which can return inode and filetype and sort
285 the names in various ways.
286 - unfortunately, utime, chmod, chown on an open file that has just
287 been written can easily block, which caused aio_copy to block the
288 process. no more!
289 - no longer rely on dst path in aio_copy when futime is available.
290
2913.19 Tue Apr 21 22:05:21 CEST 2009
292 - more perl 5.10 workarounds for aio_read and write.
293 - aio_write no longer modifies the sv (if possible).
294 - aio_read now works correctly with magic values.
295
2963.18 Sun Apr 19 21:17:32 CEST 2009
297 - better diagnostics when some aio_* functions get passed an illegal fh.
298 - try to avoid crashes due to incompatible 5.10 API changes. grmbl.
299
3003.17 Thu Nov 20 08:45:36 CET 2008
301 - (libeio) added aio_sync_file_range (untested).
302 - add aio_busy to @IO::AIO::AIO_REQ.
303
3043.16 Wed Oct 22 18:28:01 CEST 2008
305 - use SvREFCNT_inc instead of SvREFCNT_inc_NN in a non-speed critical
306 part to improve portability to perl 5.8 (reported by szymon).
307
3083.15 Mon Oct 13 00:39:55 CEST 2008
309 - automatic removal of feeders was broken.
310 - (libeio) use a more robust method to detect whether a feeder
311 has added something to the group or not.
312
3133.1 Thu Oct 2 13:34:40 CEST 2008
314 - pre-deref the passed callback object, for increased speed
315 and decreased memory usage.
316 - call on_next_submit callback even for aio_group - impact unknown,
317 but seems more correct.
318 - $req->cb now returns the original callback.
319 - (libeio) pass EIO_GROUP/aio_group requests through the queue without
320 requiring a thread switch.
321 - (libeio) status code of aio_futime and aio_utime was always passed 0.
322 - do some other ยต-optimisations.
323
3243.07 Sat Aug 2 16:06:13 CEST 2008
325 - do not include LIBS in autoconf tests.
326
3273.06 Tue Jul 15 12:41:32 CEST 2008
328 - move preadwritelock definition before it's first reference,
329 to make it compile again on broken platforms (they still exist)
330 or badly cofngiured perls (redhat...), reported by Rob Bloodgood.
331
3323.05 Thu Jun 19 23:23:52 CEST 2008
333 - work around perl overriding readdir etc. with thread-unsafe
334 (sic!) versions.
335
3363.04 Wed Jun 18 01:35:38 CEST 2008
337 - (libeio) fix eio_mknod, which confused it's arguments.
338 - (libeio) do not use readdir_r, as Ulrich Drepper pointed out that this
339 is stupid.
340 - (libeio) fix eio__readahead prototype, patch by Jost Krieger.
341 - (libeio) fix a bug that could potentially cause IO::AIO
342 not to get initialised properly.
343
3443.03 Thu May 29 05:33:30 CEST 2008
345 - (libeio) correctly call pthread_attr_destroy ().
346 - (libeio) work around broken bsd headers once more.
347 - reduce shared library size again by not including wrappers.
348 - max_outstanding could cause poll to enter a busy-waiting loop.
349 - document the new IO::AIO::poll_cb result value.
350
3513.02 Mon May 12 02:32:02 CEST 2008
352 - fix a memory leak on aio_readlink.
353 - bring back working fchmod.
354 - nop and busy now set result to 0.
355 - set errno to ENOMEM when allocation fails.
356
3573.01 Sun May 11 03:07:03 CEST 2008
358 - (libeio) make it compile on systems without readahead or readdir_r.
359 - (libeio) improve configure check for readahead availability.
360 - do not try to link against -lrt.
361 - use a separate configure script for IO::AIO (not the libeio one).
362
3633.0 Sun May 11 00:57:14 CEST 2008
364 - added bin/treescan to the distribution.
365 - switched to using libeio.
366 - LOTS OF INCOMPATIBLE CHANGES:
367 - remove signal functionality, it is not worth the effort.
368 - max_outstanding no longer returns the previous number of requests.
369 - poll_cb no longer returns number of requests.
370
3712.62 Sat Apr 26 13:59:33 CEST 2008
372 - port to solaris perls configured for old posix
373 (analysed by Jost Krieger).
374 - keep a reference to the perl filehandle object in aio_close,
375 so it doesn't get closed prematurely, leading to ugly races.
376
3772.61 Wed Apr 16 18:45:02 CEST 2008
378 - fix treescan output duplication and improve output ordering.
379 also display files given on the commandline.
380 - use a different algorithm for aio_close that is faster
381 and probably has even lower chances of blocking.
382 - do our own stack memory management for threads - linux
383 allocates outrageous amounts of VM (not so bad unless you
384 use mlockall...), which severely limits the number of threads
385 on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN
386 and 4096 * sizeof (long) (usually this is 16..64k).
387
3882.6 Sun Mar 30 08:28:11 CEST 2008
389 - added aio_sync.
390 - added aio_pathsync.
391 - fix prototypes of (void) functions.
392
3932.51 Sat Oct 6 16:04:54 CEST 2007
394 - perlio isn't generally threadsafe, so aio_close could not work reliably.
395 aio_close now tries a safe hack that might not be that asynchronous
396 (see the manpage for details).
397 - discard callback return values as to not grow the stack endlessly
398 when poll_cb handles many requests without returning.
399 - minor code cleanups.
400
4012.5 Thu Oct 4 14:49:08 CEST 2007
402 - replaced _fd2fh with faster xs code.
403 - aio_close will now try to do "the right thing" and thus might
404 work sensibly for the very first time.
405
4062.41 Mon Sep 24 21:28:21 CEST 2007
407 - after fork, invest some work to make sure that the poll_fileno
408 stays stable (by dup2'ing the new fd over the old one), to make
409 it easier for programs/libs that don't control their forking
410 behaviour and cannot recreate their watchers.
411
4122.4 Sun Aug 5 18:44:22 CEST 2007
413 - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
414 successfully demonstrated that you can block on futimes...).
415 - allow undef as fileoffset for aio_read/write and use read/write(2)
416 internally (useful for sockets or O_APPEND handles).
417 - allow undef for length in aio_write.
418 - negative dataoffsets work as expected now in aio_read/aio_write.
419 - use NV instead of UV for 32 bit perls and file offsets, as NVs
420 have a larger range then.
421 - shared code between BDB and IO::AIO.
422 - aio_busy was completely broken. now fixed.
423 - readahead emulation now returns something.
